Timing Chain
The timing chain synchronizes your engine's internal parts and is built to last, but it can stretch or wear over high mileage. A rattling noise or warning code often signals it needs attention. Replacing a worn chain protects your engine and restores smooth, reliable performance.

Frequently asked questions
How do I know if my timing chain is going bad?
A rattling noise on startup, a check engine light, or rough running are common signs. A mechanic can confirm with a scan and inspection before recommending replacement.
Does a timing chain need regular replacement like a belt?
Timing chains are designed to last much longer than belts and often go the life of the engine. They're usually replaced only when they stretch or wear, not on a fixed schedule.
